The invention relates to a catalyst composition suitable for conversion of alkanes having 3 to 12 carbon atoms per molecule to aromatic hydrocarbons, wherein the catalyst composition comprises M N /M A /Ga-zeolite, wherein M N stands for noble metals and M A stands for alkali metals and/or alkaline earth metals, and wherein M N /M A /Ga-zeolite is a zeolite comprising 0.01 -10 wt % of M N with respect to the total M N /M A /Ga-zeolite, 0.01 - 10 wt % of M A with respect to the total M N /M A /Ga-zeolite and 0.01 - 10 wt % Ga with respect to the total M N /M A /Ga-zeolite. The invention also relates to a process for the preparation of said catalyst composition and to a process for the production of aromatic hydrocarbons comprising the step of contacting a feedstream comprising an alkane selected from the group of alkanes having from 3 to 12 carbon atoms per molecule and any mixtures of alkanes having from 3 to 12 carbon atoms per molecule with said catalyst composition to form aromatic hydrocarbons. |
